Storage and Disposal of Spent Fuel and High Level Radioactive Waste
ثبت نشده
چکیده
2. Nuclear fuel consists of fuel pins that are stacks of uranium oxide or mixed uranium plutonium oxide (MOX) cylindrical ceramic pellets, with diameters of 8–15 mm, that are encapsulated in metallic tubes. The fuel pins are grouped together in fuel assemblies. Each fuel assembly can be handled as a single entity, thus simplifying the fuelling and defuelling of reactors and the subsequent handling of spent nuclear fuel.

At the Ignalina nuclear power plant (NPP), app. 22 thousands of spent nuclear fuel (SNF) assemblies from the RBMK-1500 type reactor have been accumulated [15]. During the operation of Ignalina NPP, the assemblies of SNF were stored in water pools and in storage containers, located in the interim storage facilities. According to revised Lithuanian Strategy for Management of Radioactive Waste [20...

The OECD NEA (Nuclear Energy Agency) anticipates that by 2050 the amount of nuclear-generated electricity worldwide will increase by a minimum of 1.6 times and a maximum of 3.9 times its 2008 value of 372 GWe [1]. At the same time, the amount of radioactive waste that will be produced is expected to increase substantially. High-level radioactive waste is usually derived from the burning of uran...
